Description

Technical Field

[0001] The utility model relates to the technical field of garbage landfill, in particular to a device for detecting liquid level of leachate in a garbage landfill. Background Art

[0002] Landfill is the process of transporting domestic waste generated in human life to a landfill site, where the waste is decomposed through landfill isolation and microbial degradation technology. During the stacking process, the waste will produce leachate as it degrades, and sometimes rainwater will penetrate into the waste. At the same time, some harmful gases will be produced during the degradation process of the waste, and pipes need to be used to discharge the gases in time. When the liquid level inside the landfill is too high, the pore water pressure in the garbage pile increases, and at the same time, its soil mechanical properties parameters (cohesion and internal friction angle) decrease significantly, resulting in a significant reduction in the safety of the slope and even possible instability, affecting the structural safety of the landfill. In addition, when there is too much liquid inside, it is easy to cause gas pipeline blockage and damage the vacuum equipment.

[0003] Therefore, real-time monitoring of the liquid level inside the landfill is crucial, but common liquid level sensors or liquid level detection devices need to ensure that the liquid surface is not blocked by other garbage, which is difficult to ensure in actual situations. Usually, due to the obstruction of garbage, traditional liquid level detection devices or sensors cannot accurately detect the liquid level. Therefore, a landfill leachate level detection device is proposed to solve the above-mentioned problems. Utility Model Content

[0004] In view of the shortcomings of the prior art, the utility model provides a landfill leachate level detection device to solve the problem that the existing level detection device is easily affected by garbage obstruction when detecting the landfill leachate level, resulting in inaccurate detection results.

[0005] The utility model provides a technical solution to the above-mentioned technical problem as follows: a landfill leachate level detection device, comprising: a fixing frame, a float-type liquid level sensor, a main sleeve and a bottom cylinder with holes are sequentially connected with the fixing frame from top to bottom through a partition rod and a nut, a fixing ring is arranged on the outside of the bottom cylinder with holes through screws, and a fixed guardrail is arranged between the bottom cylinder with holes and the fixing ring.

[0006] On the basis of the above technical solution, the present invention can also be improved as follows.

[0007] Furthermore, the fixing frame includes a main frame plate, and one side of the main frame plate is provided with a first connecting plate, a second connecting plate and a supporting bottom plate in sequence from top to bottom.

[0008] Furthermore, the main sleeve includes a third connecting plate, a sleeve with a hole is arranged between the third connecting plates, and the main sleeve is arranged between the first connecting plate and the second connecting plate.

[0009] Furthermore, the bottom tube with holes is arranged between the second connecting plate and the supporting bottom plate, and the bottom tube with holes includes a fourth connecting plate, and the bottom end of the fourth connecting plate is provided with an umbrella-shaped sleeve and a supporting tube in sequence from top to bottom.

[0010] Furthermore, the lower surface of the umbrella-shaped sleeve is provided with an inclined bottom surface, and the outer surface of the umbrella-shaped sleeve is provided with a clamping groove and a threaded blind hole.

[0011] Furthermore, a positioning tube is arranged on the bottom wall inside the supporting tube, and a fixing ring is arranged on the outside of the umbrella-shaped sleeve by screws.

[0012] Furthermore, the fixed railing includes a vertical rod, and the vertical rod is arranged inside the slot.

[0013] Furthermore, blocks are provided at both ends of the vertical rod, a tilting rod is provided at the bottom end of the lower block, a contact block is provided on one side of the tilting rod close to the support tube, and the contact block contacts the surface of the support tube.

[0014] Furthermore, the dividing rod comprises a main rod body, and threaded columns are arranged at both ends of the main rod body.

[0015] Compared with the prior art, the beneficial effects of the utility model are:

[0016] 1. The utility model provides a landfill leachate level detection device, which is provided with components such as a bottom cylinder with holes and a main sleeve. Due to the matching relationship between the bottom cylinder with holes and the main sleeve, garbage is blocked outside, while garbage leachate can still penetrate into the main sleeve and the bottom cylinder with holes, ensuring that the float of the float-type liquid level sensor can float under the action of the leachate without being blocked or affected by the garbage.

[0017] 2. The utility model provides a landfill leachate level detection device, which achieves a preliminary blocking effect by setting a separation rod to prevent garbage from directly acting on the surface of the main sleeve. The setting of the fixed barrier rod can block garbage with larger particle sizes, preventing garbage with larger particle sizes from clogging the holes on the surface of the perforated bottom cylinder. At the same time, the setting of the inclined bottom surface provides sufficient obstacles for garbage with smaller particle sizes. The garbage needs to completely overcome gravity to block the holes on the inclined bottom surface. That is to say, even if the umbrella-shaped sleeve and the upper surface of the support cylinder are blocked, the inclined bottom surface will not be blocked, further increasing the ability to prevent blockage.

DETAILED DESCRIPTION

[0029] The present invention will be further described in detail below in conjunction with specific embodiments so that those skilled in the art can understand the present invention more clearly.

[0030] It should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected" and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integrally formed structure. For ordinary technicians in this field, the specific meanings of such terms in this patent can be understood according to specific circumstances.

[0031] Example 1

[0032] See also Figure 1 and Figure 5 , a landfill leachate level detection device, comprising:

[0033] A fixing frame 1, the fixing frame 1 comprising a main frame plate 11, one side of the main frame plate 11 is provided with a first connecting plate 12, a second connecting plate 13 and a supporting bottom plate 14 in sequence from top to bottom;

[0034] Based on the above structure, the fixing frame 1 serves to connect the float type liquid level sensor 6, the main sleeve 2 and the bottom sleeve with holes 3. The partition rod 7 includes a main rod body 71, and threaded columns 72 are arranged at both ends of the main rod body 71. The above three can be connected to each other through the partition rod 7 and the nut, and the float of the float type liquid level sensor 6 is located inside the main sleeve 2, wherein the main frame plate 11 can cooperate with the screws to be fixed in the landfill.

[0035] like Figure 1 , Figure 2 and Figure 6 As shown, the float type liquid level sensor 6 and the main sleeve 2 are connected to the fixing frame 1 from top to bottom in sequence through the partition rod 7 and the nut, the main sleeve 2 includes two third connecting plates 21, a sleeve with a hole 22 is arranged between the two third connecting plates 21, and the main sleeve 2 is arranged between the first connecting plate 12 and the second connecting plate 13;

[0036] The float type liquid level sensor 6 is an existing sensor, and its specific working principle and structure are all existing technologies. Here, it is only required to have the functions of a traditional float type liquid level sensor, so the specific structure and principle of the float type liquid level sensor 6 are not described in detail.

[0037] Based on the above structure, the main sleeve 2 plays a role of wrapping the float type liquid level sensor 6, providing a sufficient working environment for the float type liquid level sensor 6 and avoiding the influence of garbage on its work.

[0038] like Figure 2-Figure 4 , Figure 7 and Figure 8As shown, the bottom tube with holes 3 is arranged between the second connecting plate 13 and the supporting bottom plate 14, and the bottom tube with holes 3 includes a fourth connecting plate 31, and the bottom end of the fourth connecting plate 31 is provided with an umbrella-shaped sleeve 32 and a supporting tube 35 in sequence from top to bottom, and the lower surface of the umbrella-shaped sleeve 32 is provided with an inclined bottom surface 37, and the outer surface of the umbrella-shaped sleeve 32 is provided with a card groove 33 and a threaded blind hole 34, and a positioning tube 36 is provided on the bottom wall inside the supporting tube 35, and the outside of the umbrella-shaped sleeve 32 is provided with a fixing ring 4 through a screw and the threaded blind hole 34;

[0039] Based on the above structure, the bottom cylinder with holes 3 cooperates with the main sleeve 2 to provide sufficient working space for the float type liquid level sensor 6, ensuring that the leachate can penetrate into the bottom cylinder with holes 3 and the main sleeve 2 while avoiding the interference of garbage. Among them, the setting of the umbrella-shaped sleeve 32 and the inclined bottom surface 37 cooperate with each other, which can effectively prevent small particles of impurities from clogging the holes on the surface of the bottom cylinder with holes 3 and avoid clogging. The setting of the positioning cylinder 36 plays a role in fixing one end of the float type liquid level sensor 6.

[0040] As shown Figure 1-Figure 4 as well as Fig. 9 As shown, a fixing ring 4 is arranged on the outside of the bottom cylinder 3 with holes by screws;

[0041] A fixed guardrail 5 is arranged between the bottom cylinder with holes 3 and the fixed ring 4. Stoppers 52 are arranged at both ends of the vertical rod 51. A tilting rod 53 is arranged at the bottom end of the stopper 52. A contact block 54 is arranged on the side of the tilting rod 53 close to the support cylinder 35. The contact block 54 contacts the surface of the support cylinder 35.

[0042] Based on the above structure, the fixing ring 4 cooperates with the perforated bottom cylinder 3 to fix the fixed railing 5. When the fixed railing 5 is installed, a plurality of inclined rods 53 together constitute a bowl-shaped guardrail, forming a shielding area between the support cylinder 35 and the inclined bottom surface 37. In this way, garbage with larger particle sizes cannot break through the obstruction of the fixed railing 5, and the inclined bottom surface 37 prevents garbage with smaller particle sizes from completely adhering to its surface. In other words, even if the umbrella-shaped sleeve 32 and the upper surface of the support cylinder 35 are blocked, the inclined bottom surface 37 will not be blocked, and the umbrella-shaped sleeve 32 can play a certain protective role on the inclined bottom surface 37. Secondly, the inclined setting makes the effective area larger, thereby ensuring that the leachate can smoothly enter the interior of the perforated bottom cylinder 3.

[0043] When the device provided in this embodiment is actually used, the float type liquid level sensor 6 is connected to the fixing frame 1, the main sleeve 2 and the bottom sleeve with holes 3 through the partition rod 7 and the nut. At this time, the float is located inside the main sleeve 2 or the bottom sleeve with holes 3;

[0044] When the leachate from the landfill penetrates into the interior of the detection device from the bottom cylinder with holes 3, the float moves upward under the action of the buoyancy of the leachate to detect the level of the leachate;

[0045] In the above process, the main sleeve 2 and the bottom sleeve with holes 3 play the role of separating the garbage and the float type liquid level sensor 6, so that the float type liquid level sensor 6 can avoid being affected by the garbage during operation, and by setting the separation rod 7, it is ensured that the main sleeve 2 is less squeezed by the garbage, which plays the role of reducing the pressure of the main sleeve 2;

[0046] The arrangement of the umbrella-shaped sleeve 32 and the inclined bottom surface 37 further enhances the anti-blocking capability of the device. The inclined bottom surface 37 and the fixed barrier 5 cooperate with each other, not only blocking the garbage with larger particle size outside the fixed barrier 5, but also preventing the garbage with smaller particle size from adhering to its surface. This is because the gravity needs to be overcome during adhesion, and the gravity at this time will hinder the adhesion of small particles, so the adhesion can be avoided as much as possible.

[0047] In summary, the detection device, by setting up the main sleeve 2 and the bottom cylinder with holes 3, provides a working environment for the float-type liquid level sensor 6, which meets the actual conditions of the sensor when detecting the leachate level in the landfill, so as to achieve the effect of eliminating the interference of garbage on its detection results. It can not only intercept garbage with larger particle size, but also hinder garbage with smaller particle size to ensure that the leachate can enter the detection device.
